Redirect unauthenticated users to the sign in page
instead. Rationale:
- The content on the welcome page is what often belongs
to a separate "marketing site". The marketing content
is of no use on self-hosted instances, which typically
have new signups disabled and are for internal use only
- (the real reason, let's be honest) a number of
self-hosted instances are accessible over the public
internet. Search engines index the nearly identical
landing pages and see them as duplicated content.
